• Scoring follows best-edge practice and can be checked with a scoring plug.
• Tie breakers: judged on the first 11-point miss, starting with card #1, target #1, going in sequential order until a winner is found. This may go on to the next cards. If all 4 cards are perfect, it goes to dot wipe-out following the same process.
